Same issue here. Not updated anything else on our site just now.
Thought perhaps i needed to update this plugin, which i did (from 1.3.2 to 1.3.3) and it still happens.
Even hiding the loading animation manually, the layout of the items behind it appears to be quite broken. None of the sections are in an accordion anymore, and there’s a number ‘4’ up the top left (which appears to be the number for tab4)
Looking at the generated source code, there’s this:
Fatal error
Cannot redeclare class OAuthSignatureMethod_HMAC_SHA1 in
\wp-content\plugins\ultimate-social-media-icons\helpers\OAuth.php
on line 120
Hope that helps.
edit:
just on that error, should you perhaps not have an if(!class_exists(…)) around all of the classes in your OAuth.php?
edit2:
adding the if(!class_exists(…)) around all of the classes fixed my issue, hopefully the dev can confirm?
